Did you see this page about military aircraft serial numbers?
Few lists of MM are available here http://www.worldmilitair.com/cou%20iii.htm - just find "Italy" on the page.
Matricola Militare system has been introduced in 1923 and contains few blocks, for allocation of different aircraft' classes:
1 - 999 - prototypes, experimental, record-setters, racers
1000 - 9999 - fighters and fighter-bombers
10000 - 12999 - land-based reconnaissance and light bombers
20000 - 25999 - land-based bombers
27000 - 27999 - ship-based aircraft
30000 - 34999 - torpedo-bombers, gliders, autogyros
35000 - 35999 - maritime reconnaissance hydroplanes
40000 - 45999 - bomber hydroplanes
50000 - 56999 - trainers and touring aircraft
60000 - 61999 - cargo aircraft
65000 - 65999 - training hydroplanes
70000 - 74999 - aerobatic trainers
75000 - 75999 - assault aircraft
The list comes from "Ali Tricolori, Parte 2e - 1923-1934", (Storia Militare Dossier, 2013)
I wonder, if this designation system has been restarted after the WW2, for AMI?
